  • Human and environmental water needs can come into conflict in dam-regulated river systems. Here, Chen and Olden investigate the potential for the use of fish–flow modeling to make recommendations for the management of native and nonnative fish species whilst providing water for society.

  • Globalization facilitates the spread of invasive alien species, while environmental change can ease invasion. Here, Early et al. identify vulnerable regions globally and evaluate capacity in vulnerable countries to prevent invasions arising from sources such as air travel, horticulture, and pet trade.

  • To understand how species will cope with warming, knowledge of the thermal limits is needed. This study estimates 2,960 ray-fin fish species’ thermal sensitivity. Comparison with projected warming highlights vulnerable freshwater and marine regions.

  • A compilation of 4,476 riverine fish community time series is used to identify trends in community composition and species abundance and richness over several decades. Spatial heterogeneity in the trends is linked to the timing and strength of anthropogenic pressures, including the introduction of non-native species.

  • Hydrologic data collected from river gauges inform critical decisions for allocating water resources, conserving ecosystems and predicting the occurrence of droughts and floods. The current global river gauge network is biased towards large, perennial rivers, and strategic adaptations are needed to capture the full scope of rivers on Earth.

  • Small hydropower plants are increasingly favoured. This study finds that these plants are decreasing river connectivity in Brazil more than larger dams, potentially harming migratory fish, and suggests future dam portfolios that result in less river fragmentation while delivering similar power.

  • As the climate warms, we can’t restore waterways to pristine condition, but models can predict potential changes, argue Jonathan D. Tonkin, N. LeRoy Poff and colleagues.

  • Climatic change and human control over river flow are likely to affect aquatic species distributions. Here, the authors model alterations to natural flow regimes and show that even small modifications can have consequences for the structure of riparian plant networks.

  • Large-scale invasive species control initiatives are motivated by laudable desires for native species recovery and economic benefits, but they are not without risk. Management interventions and policies should include evidence-based risk–benefit assessment and mitigation planning.

  • Coal is an important energy source, but its use affects regional air quality and global climate. This study finds that coal mining reduces the diversity and number of stream animals and that these impacts persist after mine reclamation efforts.

  • Freshwater resources sustain ecosystems and societies, so reliable monitoring is critical. This study finds that streamgaging data reporting has declined worldwide since 1979, and that variation in monitoring threatens many US river basins.

  • Hydropower is a renewable energy source that can contribute to growing energy demands. This Review considers the ecological consequences of hydropower plants on riverine systems and emphasizes the urgent need to mitigate ecological impacts to ensure sustainable development.
